Language evolves over time but "Trader" (and to a large extent "Investor") doesn't mean what they imply it means in ads for crypto / leveraged brokerage accounts and even pension accounts. As for grifters on social media / youtube / paid for newsletters - most of the words they say or write dont mean the things they think they mean.
